COLTER- CLAMP.

SPECIFICATION forming part of Letters Patent No. 623,263, dated April18, 1899.

Application filed October 14, 1898.

To all whom, it nuty concern:

Be it known that I, HARRY WILLIAM SMITH, a citizen of the UnitedStates,residing at Paragould, in the county of Greene andState ofArkansas, have invented certain new and useful Improvements inAdjustable Colter- Clamps, of which the following is a truespecification.

My invention relates to adjustable colterclamps; and its object is toprovide an improved construction of the same whereby the colter may beadjusted vertically so as to vary its height with relation to the groundand also to be adjusted with respect to the angle at which it strikesthe ground.

The invention consists, essentially, in a col- 'ter-clamp and the novelconstruction and arrangements of its parts, a slotted bottom platesecured to the under side of the beam, a slotted top plate secured tothe upper side of the beam, provided with bolts welded or otherwisefastened to the sides and at the ends of top plate, and a clamp providedwith a cross-head and a tail-nut, the construction being such that byloosening the tail-nut the colter can be adjusted vertically orangularly, as hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 shows a side elevation of mydevice. Figs. 2, 3, at, and 5 show detailed views of the clampingmechanism.

In the said drawings the letter a designates bolts welded or otherwisefastened to the side and at the ends of the top plate 2, so that topplate 2 sits edgewise on upper side of the beam, provided with a slot 0lengthwise of plate, as shown in the drawings.

The clamp 3 is provided with a cross-head on the rear end, a bend atright angle far 40 enough to allow the thickness of top plate Serial No.693,572. (No model.)

2 and colter-shank to fit between cross-head and bend, and another bendat right angle far enough forward so that when colter-shank is drawnback as far as it will go (clamp being in slot a) clamp fits the coltershanksnugly, the forward end of clamp projecting through slot 0 farenough to receive tail-nut e.

Cross-head d is made on rear end of the clamp 3 by lugs extendingoutwardly from its sides, with the inner corners of said lugs rounded,so that when the tail-nut eis loosened the clamp releases thecolter-shank.

The bottom plate 5 is formed with a slot f and holes g and is secured inplace by bolts a, passing through the beam and holes 9, and nuts screwedon bolts a. Slot f should be even with the slot or opening through thebeam.

In using the colter-clamp pass the shank of a 'colter up through theslot f in the bottom plate and the opening through the beam and slip theclamp 3 in slot c,with the tail-nut forward. Then pass the colter-shankthrough the clamp 3 and secure it in place by tightening up the tail-nute. To adjust the colter, loosen the tail-nut 6, move the colter up ordown or back or forward to suit the ground, and then secure it in placeby tightening up the tail-nut 6.

Having thus fully described my invention, what I claim is.

A top plate 2, with a longitudinal opening 0, and formed with bolts a,welded or otherwise fastened to it, a clamp 3, with a crosshead d, and atail-nut e, a bottom plate 5, with slot f and holes 9.

HARRY WILLIAM SMITH.
